As Fig. 4 illustrated, both equations showed that blending ratios
of 50:50 biomass bio-briquette have the highest calorific value of
(Eq. (5) ¼ 16.74 MJ kg 1) and (Eq. (6) ¼ 17.16 MJ kg 1). The actual
bomb calorimeter measurements showed the 25:75 blending ratio
had the highest CV of 17.17 MJ kg 1.
